Patent EP-0239902-A3 (EP)
IPC: A61C17/00
Filed: 1987-03-23
Abstract: Das Dentalgerät weist einen Griffschaft (2) auf, in 
welchem ein Futter (9) zur Aufnahme eines Werkzeuges (3) 
vorgesehen ist. Zur Fixierung des Werkzeuges (3) ist im Futter 
(9) ein Kupplungsstift (16) gelagert, der durch eine, unter Fed­
erkraft stehende Stellhülse (11) in eine Nut des Werkzeuges 
(3) einschiebbar ist. Das Lösen und Wechseln des Werkze­
uges (3) kann durch Verschieben der Stellhülse (11) durch 
einen Betätigungsring (5) sehr schnell erfolgen, so dass 
gegenüber bekannten Dentalgerätten der Werkzeugwechsel 
wesentlich schneller erfolgen kann, was sich bei mech­
anischen Scalern besonders vorteilhaft auswirkt.

IPC: H04N7/32
Filed: 1987-04-08
Abstract: Zeitaufwendige (periodische Bild-)Signal-Analysen 
werden verkürzt, wenn eine ausschließliche Übertragung 
neuer relevanter informationen gelingt. Durch Speicherung 
vergangener (relevanter) Informationen bedürfen nur die 
zeitlich-örtlichen GEBIETE mit SIGNAL-RELEVANZ bzw. re­
levanter Signal-Änderung der (erneuten Analyse und) Über­
tragung. Aufgabe der Erfindung ist eine (IR-)RELEVANZ-­
BEREICHS-ANALYSE SUR BESTIMMUNG VON (IR-)RELE­
VANTEN SIGNAL-GEBIETEN. Irrelevanz-Gebiete benötigen 
jeweils nur einen STÜTZ-WERT. Gebiete relevanter Funkti­
ons-Änderung liefern zugehörige RELEVANTE OFFSETS. 
OFFSET-BEREICHE jeder Relevanz sind mit DOPPEL-­
PRÄDIKTIONEN definierbar.  
     BEREICHS-PRÄDIKTIONEN nutzen für ganze BEREI­
CHE MINIMAL-CODIERUNGEN nach Prädiktionen einer mehr-­
parametrigen ERWARTUNGS-MENGE. Das liefert bereichs-­
abhängig verkürzte Code-Längen auch für PCM-QUALITÄT! 
In jedem BEREICH kann man sukzessiv (z.B. top-down bis 
zum realen Funktionswert) fortfahren, sowohl örtlich-zeit­
lich als auch in der Luminanz, auch mit 1-bit-DOPPEL-­
PRÄDIKTIONEN.  
     Gespeicherte Bilder gestatten nun durch (punktweise) 
DIFFERENZEN-BILDUNG zu zeitlich-örtlichen Nachbarpunk­
ten der Speicherung von XYZ-GRADIENTEN-BILDERN, wo­
mit (IR-)RELEVANZ-BEDINGUNGEN auch als BINÄR­
MUSTER marklerbar sind. Dann werden LOKALE BEREI­
CHE der BEWEGUNGEN und UNSCHÄRFEN zu zählbaren 
Bit-Mustern für die GEFÄRDUNGS-BEREICHE und OFF­
SETS, die nun, präventiv ermittelt, genauer prädizierbar 
und als Speicher-Werte viel schneller auswertbar sind.  
     Bereiche enthalten RELEVANTE PUNKTE wie die (rela­
tiven) Extrema. STÜTZWERTE vergleichbarer Art sind auch 
als (SEGMENTIERTE = verteilbare, D-)PCM-CODES über­
tragbar. Sind OFFSETS (etwa) bekannt, so können im RELE­
VANZ-BEREICH ORTS-PCM-CODES mit direkt offset-abhän­
gig reduzierter Länge vorgesehen werden.  
     Unvorhersehbarkalten führen zu bottom-up-Codes. Die 
(IR-)RELEVANZ-SELEKTION durch Gradienten erlaubt 
SCHWERPUNKT-BILDUNG und (IR-)RELEVANZ-BEREICHS-­
CODES.
Patent EP-0244676-A3 (EP)
IPC: G06F9/22
Filed: 1987-04-14
Abstract: A method for optimizing performance in a fixed 
clock rate computer system. A control word is provided 
having a control portion for operational instructions 
and a programmable timing portion. The programmable 
timing portion includes a value representative of the 
sum of execution time and inter-execution delay time. 
A counter (22i) is provided for receiving the value 
representative of the execution and inter-execution 
times. The counter is capable of generating a signal 
(EOS) to indicate an end of decrementing operation. 
The operational instructions are executed simultaneously 
with the processing of the time value in the counter 
so that a subsequent instruction is executed only when 
an end of operation signal is received from the 
counter.

Title: Self-timed programmable logic array with pre-charge circuit
IPC: H03K19/177
Filed: 1987-07-01
Abstract: A programmable logic array includes a decoder section and an encoder section connected by a plurality of minterm conductors. The decoder section receives a plurality of input signals and in response selects appropriate ones of the minterm conductors. The selection of the minterm conductors enable the encoder selection to transmit a plurality of output signal on respective output conductors. The decoder and encoder sections include a plurality of stages, each controlling a minterm conductor and output conductor in response to the input signals and the selection of the minterm conductor. The stages include control transistors that are connected between a node, to which the respective minterm and output conductors are connected, and switches which enable and disable the control transistors. The nodes are initially precharged while the switches disable the respective transistors. After precharge, the switches enable the transistors in the decoder and encoder section respectively. A self timing circuit controls the switches to ensure that the switches are correctly timed.

Patent EP-0308211-A3 (EP)
IPC: G06F17/10
Filed: 1988-09-15
Abstract: A signal processor receives random input signals 
from a pair of sensors such as beam sensing 
electrodes, antennas, microphones or optical 
position sensors. An estimation equation 
implemented by the signal processor uses weighted 
integration of log ratios where the weighting is 
adaptive and depends upon the values of signal 
samples being processed. The signal processor uses 
digital signal processing to provide an estimate of 
the desired parameter. Nonlinear functions such as 
hyperbolic tangent and logarithm are contained in 
programmable read only memories in order to obtain 
high speed operation. When the signal processor is 
used in conjunction with channel switching, errors 
due to channel mismatch are completely eliminated. 
In a preferred embodiment, the sensors are beam 
sensing electrodes and the signal processor is used 
for estimating the position of a scanned ion beam in 
a ion implantation system.

Title: Sealing assembly
IPC: F16J15/3268
Filed: 1988-12-16
Abstract: A sealing assembly (4) is used to seal the gap between the 
two member (1, 2) that move relative to each other. It includes 
first and second rings (5, 6) provided in a groove (3) formed in one of 
the members. A portion of the outer peripheral surface of 
the first ring (5) is in contact with the other member. None of 
the surfaces of the second ring (6) makes contact with the other 
member. The second ring (6) engages with the portion of the 
first ring (5) which is not in contact with the other member. 
The second ring (6) has a coefficient of thermal expansion 
smaller than that of the first ring (5). When the first ring (5) 
expands due to the heat generated by the slide of the first 
ring (5) against the other member, the expansion of the first 
ring (5) is limited by the second ring (6).

Title: Pipeline bubble compression in a computer system
IPC: G06F9/38
Filed: 1989-07-20
Abstract: Bubble compression in a pipelined central processing 
unit (CPU) of a computer system is provided. A bubble 
represents a stage in the pipeline that cannot perform any 
useful work due to the lack of data from an earlier 
pipeline stage. When a particular pipeline stage has 
stalled, the CPU instructions that have already passed 
through this stage continue to move ahead and leave behind 
vacant stages or bubbles. If a bubble is introduced into a 
pipeline and the pipeline subsequently stalls, the 
disclosed CPU takes advantage of this stalled condition to 
compress the previously introduced bubble.
